To all whom 2'2? may concern:

Be it known that I, ETURAJ DEDIK, a citizen of Czechoslovakia, residing at'Boswell, in the county of Somerset and State of Pennsylvania, have invented certain new and useful Improvements in Ship-Protectors, of which the followingis a specification.

This invention relates to certain new and useful improvements in ship protectors particularly serviceable for preventing capsizing of vessels in heavy seas and also of value in receiving shocks of collisions so as to minimize danger of damage to the hull of the vessel.

The invention broadly consists in anvendless hollow float loosely surrounding the hull of the vessel and associatedwith mechanism for normally holding it raised in an inoperative position and for permitting the same to lower to an operative position when required for use.

The objects of the invention are preferably carried out by the construction hereinafter more fully described, shown inthe accompanying drawings and claimed.

In the drawings forming a part ofthis application, and in which like reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevational view of a vessel equipped with a protector constructed 1n accordance with the invention,

Fig. 2 is a top plan view thereof,

Fig. 3 is a transverse sectional view taken substantially upon line IH-III of Fig. 4,

Fig. 4 is a fragmentary top plan view of the device shown in Fig. 2, with the cabin of the vessel in horizontal section and drawnon a larger scale,

Fig. 5 is a transverse sectional view taken substantially upon line VV of Fig. 4,

Fig. 6 is an enlarged detail view, partly in elevation, and partly in section, .and illustrating the clutch mechanism for rendering the protector raising mechanism inoperative at will,-and

Fig. 7 is a sectional view taken substantially upon line VII-Vll[ of Fig. 6.

Referring more in detail to the several views, the present invention includes an endlesshollow float 5 constructed of metal or any other desirable material and cone forming to the shape of the ship hull 6 as well as extending entirely around the latter p in a j ent t e Wa er l e sa d he a I Specification of Letters Patent. Pgfl gntgfl NQV. 15, 1921, 1 Application filed June 11, 1920. Serial No. 388,114.

with and extend upwardly from the floats 5 at. each side of the hull 6 and pinions 8 are rotatably mounted upon the deck of the the rear of the vessel while. a similar rack bar 10 is carried by the float at the forward end of the vessel and these rack bars 9 and 10 each mesh with an idler pinionll suitably rotatablymounted upon the adjacent portions of'the deck of the vessel. The rack bars 9 and 10 and idler pinions 11 are merely provided to steady the Heat in operation and to effectively guide the, float when being raised or lowered so as to minimize friction. i

Each pinion 8 has a bevel gear'12 rigid therewith and meshing with another bevel pinion 13 fastened upon a transversely arranged shaft 14 which-extends into the cabin 15. It will thus be seen that the forward pair of pinions' 8 are operatively geared to a pair of shafts 14 which extend inwardly toward each other, while the rear pair of pinions 8 are similarly geared to a pair of shafts 14 that also extend, transversely of the vessel inwardly toward each other within the cabin l5.

A suitable motor 16 is mounted in the cabin between the pairs'of shafts 14, and each pair of the latter are operatively geared to the shaft 17 of this motor by similar mechanism which is best illustrated 'in Figs. 3'to 5 inclusive. This involves a .4; pair of vertical rack bars 7 are rigid vided upon each shaft 14 for connecting and disconnecting the miter gear 20 thereof to the same at will So as to control the transmission of power from the motor 16 to a desired one or all of the pinions 8 when found necessary. Each clutch 21 isfprovided with an ordinary operating lever 22 so that the same may be readily manipulated.

in operation, the motor 16 is started for to place the float in use, .the'clutches 21 rotating its shaft 1 7 in one direction and,

operation of the-"present invention as well through the gearing described, the pinions 8 are rotated for causlngupward movement of the rack bars 7 .simultaneously'so that the.

float 5 is brought to an inoperative position as shown by full lines in Fig. 3 above the water line of the hull 6. When it is desired may be disconnected so that the float will lower by gravity until it strikes the water vwhereupon the clutches 21 may be again connected for maintaining the float in its operative position. which is indicated by ,themiter gears to the shafts lt and the dotted lines in- Fig. 3. However, iflfor any reason, resistance is oflered to the lowering of the float 5, by gravity, the clutches 21 may be operated for connecting motor 16 may then be started so as to rotate its shaft in a reverse directionfor causing the rack bars 7 to bemoved downwardly so as to force the float to its operative position;

, It will be obvious that when the float; 5 islowered upon the water, the same will eflectively serve as a buoy and greatly lessen the danger ofcapsizing of the vessel in rough or heavyseas and should a collision occur, the float will receive the impact and damage before damage can be doneto the hull of the vessel at its water line It is be1ieved that the construction and as the advantages of the same will bevreadily appreciated and understood by those skilled .inthe 'art and minor changes may be'made therein wlthoutdepart ng from. the SPllfll'f and scope of the invention as claimed.

A ship protector comprising in combinati'on with vesselgan endless horizontally disposed hollow float conforming toand ex tendingentirely around the hull of the vessel adjacent the waterline thereof, forward and rear pairs of'rack bars rigid Willi and extending upward from the float at. the opposite sides of the hull,- pinions meshing with saidrack bars and mounted on the deol:

of the vessel, a motor mountedon the deck of the vesselandhaving a drive shaft extending forwardly and rearwardly, driving connections between each pair of pinions. and one end of Sfild'dllVG shaft, and means to render saidv driving connections iinoper tive at will, whereby raising of said float from operative to inoperative position may be had.

In testimony whereof I-aflix my signature.
